Lead was probably one of the first metals to be produced by man, being known since 3500 B.C., in agreement with archaeological discoveries done in Egypt. The oldest lead piece is in the British Museum and dates from 3800 A.D.. The manner in which prehistoric people extracted lead from its minerals is not well-known. However, there are vestiges of very rudimentary furnaces, done of stone, where these people heated up the lead minerals with bonfires (that burned wood and coal) to extract the element Features & Applications: Although uses for lead have decreased over the years, it still plays an important part of everyday life particularly as the starter mechanism for automobiles. The lead-acid battery, which performs this function, dominates the usage of lead, consuming over 80% of world production. The remaining 20% of production is divided into numerous end-uses including: underwater cable sheathing, ammunition, glassware, solder and roof sheeting. Lead alloys are used in a range of applications including: Solder: lead solder is used extensively by the electronics industry Terne plate:iron and steel can be protected against corrosion by coating the surface with a lead based alloy. Brass and Bronze Products: lead had traditionally been used in bearings and bushings to reduce wear and friction in certain type of machinery.
